With parallel transmission / TransmitSENSE arbitrarily
shaped regions can be selectively excited with reasonable pulse durations which
allows inner volume imaging by reduction of the field of view (FOV) to excited
regions of interest. The achievable FOV reduction factor is limited by
decreasing SNR and by potentially backfolded residual signals resulting in
aliasing artifacts, which both is assessed in the present study. FOV reduction
by a factor of 4 in each direction was applied successfully to imaging of a
phantom, a kiwi and a rat in-vivo. Reduction of measurement time and enhanced
image resolution by the same factor were achieved.
